An essential tool when setting up your dishchucky03 - Casa Grande, AZ - 12/21/2013 7:33:25 PMI tried unsuccessfully to align the dish without this handy tool. This item is invaluable for aligning your Directv HD dish. Once hooked up I was able to get a good signal in both the azmuth and directional positions. You can select from two satellites to select to align. Once the meter reads max in elevation and azmuth you can not hook the dish to the TV. Of course when setting up the dish you must use the power inserter used by Directv to power the dish ( in this case an SL3) and to allow alignment of the dish. Once the settings for the dish are optimized, it may be plugged in to the TV. At this point, go to settings and find the satellite setup and go to signal strength. Check the signal of several satellites. I managed to get high eighties on one satellite and 93-100 or others. Fine tune the dish until the signal reaches the highest point and secure. That';s It.
